2zx2y=18 where x=1,z=y
Bad White [126]

\huge \bf༆ Answer ༄

Let's plug the given values and find value of y ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:2zx2y = 18

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:2 \times y \times 1 \times 2 \times y = 18

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:4 {y}^{2}  = 18

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:{y}^{2}  =  \dfrac{18}{4}

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:y {}^{2}  = 4.5

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:y =  \sqrt{4.5}

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:y =  \sqrt{9 \times 0.5}

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:y = 3 \sqrt{ \frac{5}{10} }

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:3 \sqrt{ \frac{1}{2} }

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: \dfrac{3}{ \sqrt{2} }

or, you can further simplify it to ;

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:2.12 \:  \:  (upto \:  \: two \: decimals)
